IMPROVED APPARATUS FOR DISTILLI NG SPIRITS.

i an firlnhule nfemh in in this: anon stint in mating and at the 5mm.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ANDRE FOUBERT, of the city and State of New York, have invented and made a certain new and useful Improvement in Distilling Apparatus for Spirits; and I do hereby declare the following'to be a full, clear, and exact description'of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- V 7 Figure 1 is a vertical section of the said still, fitted with my improvement; and

Figure 2 is a plan at the lines: a.

Similar marks of reference denote the same parts.

The nature of the said invention consists iu a rectifying apparatus introduced in the top part of the still itself, said device efi'ecting a partial rectification of the spirit before it leaves the still. This rectifying apparatus is formed of a series of'diaphragms, with tubes rising'througir the condensing'liquid upon such diaphragms, and caps to direct the vapors into such liquid. i r

In the drawing, a is the still, provided with the steam coil 6, glass gauge 0, testing apparatus 01, and charging and discharging pipe and cock e. f is a man-hole, that may be provided for cleaning the still. 9, h, andi are diaphragms, set tightly within the still a. Each diaphragm has several short pipes it: introduced through it, and risingtabove'the same,-the said pipes terminating with caps l. 'm m are overflow pipes, and n is the return pipe to the still. o o are pipes and cooks, by'which the liquid lying upon the diaphragms is moreor less refrigerated, so as to maintain the desired temperature of such liquid, by allowing water to run through such pipes. Arm-holes and caps may be provided, as at s, for cleaning or repairing the rectifying apparatus.

The operation is as follows The still a is filled with the light wine or spirit about two thirds its capacity. Water, on commencing the operation, has also to be admitted upon the diaphragms to near the level of the top of the overflow pipes m m. Steam is admitted by the coil 6; and when the alcohol commences to pass over, as determined by the testing apparatus d, the vapors are partially rectified by passing through the tubesla, and

below the caps Z, and .finally away by the pipe to a rectifying column or condensing apparatus ef'any usual character. The condensed v-apor's arereturned in the form of water, with little or no spiritflio the still bythe pipes mm. The temperature of the liquid on the diaphragms g, h,-and 2' is maintained by the water running through the pipes 0 o 0. When one charge has been distilled and drawn off, another charge is admitted into the still. The tubes In, with the caps I, may be arranged in rows, as in fig. 1, or in a circle, as in fig. 2; and a division, q, may be made on each diaphragm to cause the liquid to circulate around said division in passing from one pipe 101 to the neirt; and a. pipe and cook may be provided at 1' to draw away the waterof condensation, instead of allowing it to run back into the still.

What I claim, and desire to secureby Letters Patent, is-

The still a, into which the diaphragms g h i, pipes k, and caps Z are introduced, the water being returned to the still by the pipes m n, and the temperature of the. liquid on the diaphragms being requlated by water flowing through the pipes o 0,, as set forth. I p l In witness whereof I have hereunto set my signature this twenty-fifth day of Iliebruary, A. 1). 1867.
